Newport’s High performance Optical Power Meter models, 1918-C, 1918-R, 1928-C, 1936-C, and 2936- C, use large, high contrast color TFT screens to provide crisp readings and flexible displays. Current display technology offers an expected display lifetime of 20,000 hours. Earlier versions typically had the lifetime of approximately 10,000 hours. When the optical power meter is used in 24/7 settings for 365 days, which is not an unusual setting for many high volume manufacturers, 10,000 and 20,000 hours translates into only 1.14 years and 2.28 years, respectively. Recognizing these limitations, we have employed several screen saver features to help extend the display usage time and help environments by saving energy.
